UNITED STATES PATENT; OFFICE WILLIAM RUPERT ALLEN, OF HOLGOMBE, NEAR BURY, ENGLAND MEAN FOR THE MANUFACTURE OF YARNS SUITABLE FOR USE IN THE IRODUCTION' OF FABRICS THEREWITH Application iiled July 6, 1931, Serial No. 548,950, and in Great Britain September 12, 1930.

The invention relates to the manufacture of yarns such as of cotton, worsted, woollen, cut artificial silk, jute and the like, which yarns are composed of strands or fibres which are in an untwisted, that is to say, twistless condition as understood in the cotton or like industries. Said twistless yarn is capable of use in the production of fabrics, for example for forming the weft portions thereof, or of other useful applications.

According to my invention, roving's or fibres of material such as emerge from between the delivery rollers of a set of draw rollers in a ring spinningframe, or known drafting system, aresuitable for my purpose,

and which are here termed twistless.

These twistless fibres are, according to my invention, carried forward in a dry state, and afterwards subjected to a wetting process with a suitable adhesive. 7 Means are also provided for bringing said wet fibres of each group thereof into close contact with each other, whereby they may be attached together. While so attached the several groups are dried, either artificially by the application of heat for the purpose, or naturally in the open air where the last-named process is desirable or necessary.

The means for carrying out th bovenamed process may include suitable c riers or bands, one or more of which may be Wetted with an adhesive referred to for application to the fibres named passing on said band orbands. In addition, a sidewise or vibratory motion laterally considered may be imparted to a carrier or band or to a member adjacent thereto, whereby the strands may be rolled .or brought together for the purpose in view. On account of the frail or tender nature of the strandsor fibres to be combined together to form a thread according to my invention, it is necessary for said fibres, which are in parallel formation, to be rolled together in a par- 1 ticular manner, that is to say by passing between members, one of which has a sidewise movement-relatively to the other, said movement' being reciprocatory in character.

With reference to the accompanying draw ing, Fig. 1 is a side view, in sectional elevation, of a frame and parts relating to the same, showing one application of my inven tion thereto, by way of example. Figs. 2, 5, 6, 7 and 8,-show portions of the arrangements according to said'invention, or modifications thereof, all of which figures, including Fig. 1 being more or less in diagram form.

Fig. 3,is a View in plan, and on an enlarged scale, of a detail included in the figures already named, and Fig. 4 is an enlarged View of another detail herein referred to.

In Fig. 1 a container for fibrous material referred to is shown at 1 mounted in an up right position on a frame indicated at 2. The fibres before, during and after treatment, are marked 3 in the drawing. Said container is assumed to be provided with rovings or fibrous material of a nature such as is known tobe used behind any ordinary set of draw rollers, which fibrous material is shown being drawn therefrom by the rollers indicated at4 of a drafting system, from the delivery rollers of which system the fibres emerge in a twistless condition already referred to. In the various figures the reference numeral 5 refers to delivery rollers whether parts of a drafting system or not. It is understood that the parts shown in Fig. 1' are those employed for operating upon the several parallel fibres or strands intended to be combined into a single length of twistless yarn, and that other sets or like parts adjacent, and parallel to the foregoing may be provided in the one frame. It is also 0bvious that the invention is not affected whether the material for any one set comes from a single container such as 1, or from several containers or other sources, from which the fibres for one set according to Fig. 1, for example, converge towards the particular drafting rollers or delivery rollers involved. Where the fibres are in the twistless condition at the containers, the use of drafting rollers may not be necessary.

After leaving the delivery rollers 5, the fibres (in the case of Fig. l) and in the form of a thin, twistless sliver, are immediately carried forward by a travelling band 6, and

from the same, across a gap, to a further travelling b'and 7.- The last named band is kept wetted by a suitable liquid adhesive by means of a revolving roller 8 carrying said band, adjacent to a lower roller 9, and which roller 9 is'situated within a trough 10 containing said liquid, as will be understood. The surplus liquid is returned to the trough 10 by a rubber-coated or other like device shown at 11 in contact with the lower side of the band 7. The fibres of material in ,a group or sliver are thus provided with an adhesive for attachment purposes before said fibres pass the revoluble roller 12. This roller is here assumed to be revolubly mounted upon arms projecting from a shaft or bar 13 the latter capable of a reciprocatory longitudinal motion for the purpose of giving to the roller 12 a lateral vibration or alternating transverse motion. This lateral vibrating motion gives a movement to the fibres of the yarn tending to bring the same closer together for attachment purposes. One way of attaining this lateral movement is illustrated at Fig. 3. The shaft 13, work? ing in bearings at a squared part of the former, is provided with a strap 15 pivoted thereon and an eccentric disc 16, the latter in.

connection with a pulley 17, below, suitably driven by a belt 18 by applied power of any suitable kind.

In Fig. 3'the roller 12 of an adjacent unit or set of parts is indicated.

After leaving the roller 12, the wetted fibres are shown passing under a pulley-like wheel 19. As indicated in Fig. 4 this wheel is formed with a groove forming a sharp or acute angle at its inner end, which groove so shaped forms a further method of bringing the fibres closely together, or for keeping them so together. The yarn or attached fibres as finished is shown being wound upon a container or cheese indicated at 20, and between roller or wheel 19 and said cheese the yarn or thread 3 may receive its final drying operation, here attained by exposure to the open air.

But artificial drying may be adopted if desired, before the yarn passes to the cheese such as 20. The tube 22 in Fig. 1 could be one supplied with hot fluid for said drying purpose. 7

In Fig. 2 the travelling band such as 6 in Fig. 1 is-omitted, and the fibres 3 pass in the dry state directly to the wetted band 7 and are finally wound upon a swift outlined at 21, assumed to be revolubly mounted.

In Fig. 5 the fibres are wetted with the adhesive after leaving the band such as 7 by passing over a roller 23 revolved in a liquidcontaining trough 24. Fig. 6 shows a similar arrangement to Fig. 5 but with the band such as 7 dispensed with.

Fig. 7 shows an arrangement whereinthe finished yarn is wound upon a cheese situated above the roller 12 herein referred to. In

this case said yarn would pass partly round roller 12for the purpose.

In Figf8 the last named roller is dispensed with, and if the shafts of the rollers carrying the band 7 were provided after the manner illustrated in Fig. 3 a lateral vibratory movement could be imparted to said band for bringing the fibres closer together prior to said fibres in yarn forin being wound on the cheese such as 20, or on some other kind of yarn container.

A suitable adhesive for my purpose herein named may be prepared for example in the proportions of 9 oz. of glue dissolved in one gallon of hot water. But ordinary size as used in slasher sizing machinesand the like, may be permissible.

1. Means for the manufacture of yarns suitable for use in the production of fabrics, or for other purposes, from twistless slivers of fibres of roving material, comprising an adhesive-supplied carrier for said twistless fibres, and for wetting the latter with said adhesive, a moving device and a closely adjacent carrier, between which device and carrier the fibres are passed, said movement of the device being a reciprocatory and sidewise one relativedy to said carrier, whereby the fibres are rolled closer together for attachment purposes, and a device for exposing thetwistless fibres so attached to a drying agent, as herein set forth.

2. Means for the manufacture of yarnssuitable for use in the production of fabrics, or for other purposes, from twistless slivers of fibres of roving material, comprising a carrier for said fibres of a dry character, a further but adhesive-supplied carrier for said twistless fibres and for wetting the latter with said adhesive, a moving device and a closely adjacent carrier, between which device and carrier the fibres are passed, said movement of the device 'being a reciprocatory and sidewise one, relatively to said carrier, whereby the fibres are rolled closer together, for attachment purposes, and a device for exposing the twistless fibres so attached to a drying agent, as herein set forth.
